The lasers are parallel....it allows for object scale to be quickly determined.

As for the corals, there are a few things that they want to do. One is collect tissue samples to do genetic analysis to determine how genetically isolated the species in the canyon are from the rest of the world. The other thing they want to do is determine the ecology of different hard corals in bodies of water with different levels of carbonic acid, which has real world implications in better understanding how our reefs globally will respond to the inevitable acidification of our waters due to increased atmospheric CO2.

There's other 5hit being done also....for starters, they may try and retrieve the underwater glider that was lost in this exam same spot years ago.
